IF and IF NOT commands in batch file

There are three variations of the IF and IF NOT commands.

• IF EXIST: Execute the commandline only if a particular file exists:

  IF EXIST some.txt COPY c:/some.dll %windir%/SYSTEM/some.dll

• Compare two text strings, and execute the commandline only if they are identical.

  IF %HostWinBootDrv%==C SET WinDir=C:\WINDOWS

• Error testing: Check the exit code of the most recently run program. If it is equal to or greater than the number specified, execute the command:

  IF ERRORLEVEL 4 ERASE trashfile.tmp /P

The better way to understand this command is try it yourself.
If got any question, post it here. I will try my best to solve it.

GOTO Prompt

:RemoteDesktopOn
@reg add "\\%TargetMachine%\HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f
GOTO Prompt

::Listing 5: RDOff.cmd
:RemoteDesktopOff

Copy and save it the name as you like.

This batch file can use to check for your remote desktop status either on or off. On the other hand, you can also use it to turn on or off of your remote desktop.
